Nov 21 (Reuters) - Silvercorp Metals Inc (SVM.TO) said on Monday it will buy China's SX Gold Mining Company for about $23 million, in a move aimed at consolidating its holdings in China's Henan province.
Silvercorp's Henan Found Mining Co subsidiary signed a share purchase agreement to acquire a 100 percent equity interest in SX Gold, following an auction arranged by the Luoyang City government to sell the asset.

Following the KPMG report last month, Silvercorp Chief Executive Rui Feng said the company would now refocus on building value for its shareholders through ventures such as mining, exploration and resource development.
SX Gold owns the XHP silver-gold-lead-zinc mine located 120 kilometres (74 miles) southwest of its Ying mine. The XHP mine is also located just 6 km away from the XBG mine, which it acquired in August.
The company said it has already paid $19.6 million toward the acquisition and the balance is due on the completion of the transaction and transfer of mining permits to Henan Found.
